ApplicationsTo cool inverters in applications such as transport and wind turbines demanding long service life and weight benefits .

Most frequently used pumped mediumA water-glycol mixture is used as the pumped medium in most cases . However, it is also possible to use alternative non-explosive media .

DirectivesThe LC series has been designed according to Standard CLC/TS 50537-3 for railway applications . This is also reflected in optimum corrosion protection and highest fire protection according to EN 45545-2 .

Type / designHorizontal, volute casing pumps without shaft seal in process design with fully enclosed, single-stage and single-flow canned motor . The connection dimensions of the housing correspond to SAE 2" according to ISO 6162-1 .

DriveThe rotor lining – one of our core competencies – is manufactured by impact extrusion and, as a stainless steel alloy, is an essential compo-nent of the highly efficient canned motor . The liquid-filled canned motor accelerates to operating speed within seconds and operates wear-free and maintenance-free in continuous operation due to the hydrodynamic plain bearings . The canned motor is low-noise and low-vibration and offers double security against leakage .

How the LC pump works

To cool the motor and lubricate the plain bearings, part of the flow is branched off at the periphery of the impeller and, after flowing through the motor, returned to the suction side of the impeller through the hollow shaft . This design is suitable for pumping non-critical liquids with low vapour pressure .

Partial flow return to the suction side

Bearings

The hermetically sealed design requires the arrangement of bearings in the pumped liquid . Therefore, only hydrodynamic plain bearings are used in HERMETIC pumps . With correct operational mode, these bearings have the advantage that there is no contact between the bearing sliding surfaces . As a result, they are wear-free and maintenance-free in continuous operation . A service life of 20 years is common for hermetically sealed pumps .

In refrigeration engineering, carbon graphite is used as the bearing bush material that can withstand particularly high radial and axial loads . In addition, the material has a high resistance to elevated and low temperatures and high fatigue strength .
